In the case of S-polarized light, the first polarization beam splitter 142 will wavelength Light below 485 nm (nm) reflects, while light above 485 nm (nm) will penetrate the first polarizing beam splitter 142. Therefore, the first blue light B1 and the second blue light B2 (first mode) of the blue output unit 300 outputting the S-polarized light are reflected by the first polarization beam splitter 142. At the same time, the first photoluminescent element 132 is excited by the yellow light and passes through the first polarizing beam splitter 142.

Returning to FIG. 1 , the first wave plate 162 in the first optical module 122 is a quarter wave plate. When the light penetrates the first wave plate 162, the light produces a phase difference of one quarter wavelength before and after the penetration. The lens group 180 includes a first lens 192 and a second lens 194. The common configuration of the first lens 192 and the second lens 194 can focus the light passing through the lens group 180 on the first photoluminescent member 132.

The light provided by the first mode and the second mode is finally guided by the second optical module 120 and the first optical module 122 to be finally directed to the multi-band filter 150. According to an embodiment of the invention, the multi-band filter 150 enables the light beam having a wavelength range falling within the first band or the second band to be reflected by the light beam of other wavelength ranges.

The characteristics and uses of the elements of the six primary color solid-state light source 100 of the present invention have been described in detail above. In the following description, the optical path output focusing on the first mode and the second mode will be described.

[First Modal]

Referring to Figure 7, it is a schematic diagram of the optical path of the first mode of the six primary color solid state light sources of the present invention. The optical path description in this embodiment will be described in conjunction with the spectrum of the first polarization beam splitter 142 of Fig. 5 and the spectrum of the multi-band filter 150 of Fig. 6. In addition, for convenience of explanation, the blue light output unit 300 in the drawing and the description outputs the first blue light B1 of the S polarized light and the second blue light B2 (the first mode) and the yellow light emitted by the first photoluminescent element 132. Light is only described by one light. And the blue light output unit 300 outputs the first blue light B1 of the S-polarized light and the second blue light B2 (the first mode) as the first combined light beam 118 and the first light-emitting element 132 emits a yellow light beam 119. First described.

The first combined beam 118 is aligned with the first polarizing beam splitter 142, and the first turn 204 of the stack 200 is disposed between the first polarizing beam splitter 142 and the first wave plate 162. The first combined beam 118 is S-polarized with respect to the first polarization beam splitter 142, and as shown in FIG. 4, the first combined beam 118 will be reflected by the first polarization beam splitter 142. The first combined beam 118 is reflected by the first polarizing beam splitter 142 and penetrates the first wave plate 162 and is focused on the first photoluminescent member 132 through the guiding of the lens group 180.

Next, a portion of the first combined beam 118 produces a reflection at the first photoluminescent member 132, and another portion of the first combined beam 118 excites the first photoluminescent member 132. Therefore, the first photoluminescent element 132 is excited to emit a yellow light beam 119, The reflected first combined beam 118 and the yellow light beam 119 travel in parallel with the original incident direction of the first combined beam 118, and are again transmitted through the lens group 180 to be uniformly emitted after diffusion.

Since the first combined beam 118 penetrates the first wave plate 162 each time, it will produce a phase difference of a quarter wavelength. The first combined beam 118 passes through the first wave plate 162 one time before and after the first photoluminescent element 132 reflects, and will produce a phase difference of one-half wavelength. Therefore, after the first combined beam 118 undergoes a change in the phase difference of one-half wavelength, it is converted to P-polarization with respect to the first polarization beam splitter 142.

As further shown in FIG. 4, the P-polarized first combined beam 118 has a wavelength position corresponding to that of the first polarization beam splitter 142. On the other hand, the yellow light beam 119 is also penetrated corresponding to the first polarization beam splitter 142.

Therefore, the first combined beam 118 and the yellow beam 119 that are directed from the first photoluminescent member 132 toward the first polarizing beam splitter 142 will penetrate the first polarizing beam splitter 142. According to an embodiment of the invention, the interface between the first meandering 204 and the total reflection gap 206 is configured to allow the first combined beam 118 and the yellow light beam 119 from the first wave plate 162 to pass through and to the multi-band filter. 150.

Please see FIG. 6 again. In the penetration spectrum of the multi-band filter 150, when the first combined beam 118 is incident on the multi-band filter 150, the first blue light B1 in the first combined beam 118 will be multi-band filtered. The slice 150 is reflected, and the second blue light B2 passes through the multi-band filter 150. At the same time, the yellow light beam 119 of the first photoluminescent element 132 is from 480 nanometers (nm) to 700 nanometers (nm). When the yellow light beam 119 is incident on the multi-band filter 150, the yellow light beam 119 wavelength Light between 536 nanometers (nm) and 622 nanometers (nm) (including red light R1 and green light G2) will be reflected by the multi-band filter 150. According to the above optical path arrangement, the first combined beam 118 and the yellow light beam 119 are incident in parallel with each other and reflected more The frequency band filter 150, and when the first combined beam 118 and the yellow light beam 119 reflect the multi-band filter 150, the first blue light B1 and the yellow light beam 119 having the yellow light parallel to each other will together form a first primary color combination ( B1G2R1). Finally, the interface between the stack 200 and the total reflection gap 206 reflects the first primary color combination from the multi-band filter 150 to the direction 102 as indicated by the arrow to complete the first primary color combination in the six primary color solid state light source 100. Output.

[Second mode]

Referring to Figure 8, it is a schematic diagram of the optical path of the second mode of the six primary color solid state light source of the present invention. The optical path description in this embodiment will cooperate with the second polarization beam splitter 140 of FIG. 3 to penetrate the spectrum, the green light reflector 141 of FIG. 4 penetrates the spectrum, and the multi-band filter 150 of FIG. 6 penetrates the spectrum for explanation. . In addition, for convenience of explanation, the blue light output unit 300 in the drawing and the description outputs the first blue light B1 of the P-polarized light and the second blue light B2 (the second mode), the red light source 112, and the second photoluminescent element. The light emitted by 130 is illustrated by only one light. Moreover, the blue light output unit 300 outputs the first blue light B1 of the P-polarized light and the second blue light B2 (the second mode) as the second combined light beam 115, and the second light-emitting element 130 emits the green light beam 116 and The red light source 112 emits a red light beam 117, which is described first.

The second combined beam 115 and the red beam 117 are emitted to the second polarization beam splitter 140, wherein the second combined beam 115 and the red beam 117 are both P-polarized with respect to the second polarization beam splitter 140. Therefore, as shown in FIG. 3, the P-polarized second combined beam 115 and the red light beam 117 will penetrate the second polarization beam splitter 140. Next, the second combined beam 115 will be directed toward the second photoluminescent element 130, and the red beam 117 will be directed toward the multi-band filter 150.

The second combined beam 115 penetrates the second polarizing beam splitter 140 and the second wave plate 160 and then enters the second photoluminescent device 130 through the lens group 180, wherein The second combined beam 115 is focused on the second photoluminescent element 130 through the guidance of the lens group 180.

Then, a portion of the second combined beam 115 produces a reflection at the second photoluminescent element 130, and another portion of the second combined beam 115 excites the second photoluminescent element 130. Therefore, the second photoluminescent device 130 is excited to emit the green light beam 116, wherein the reflected second combined light beam 115 and the green light beam 116 travel in parallel with the original incident direction of the second combined light beam 115, and pass through the lens group 180 again. Guided by the lens group 180, the light is diffused and uniformly directed toward the second polarization beam splitter 140.

Since the second combined beam 115 penetrates the second wave plate 160 each time, it will produce a phase difference of a quarter wavelength. That is to say, before and after the second combined light beam 115 is reflected by the second photoluminescent element 130, it penetrates the second wave plate 160 once, so that a phase difference of one-half wavelength is generated. The second combined beam 115, which is originally P-polarized with respect to the second polarization beam splitter 140, is converted to S-polarized relative to the second polarization beam splitter 140 after a change in phase difference of one-half wavelength.

As shown in FIG. 3, the second combined beam 115 is reflected by the second polarization beam splitter 140 under S polarization. As described above, the green light beam 116 generated by the second photoluminescent element 130 is reflected by the green light reflecting plate 141.

Therefore, the second combined beam 115 and the green light beam 116 that are emitted from the second photoluminescent element 130 toward the second polarization beam splitter 140 are reflected by the second polarization beam splitter 140. The second polarization beam splitter 140 and the second wave plate 160 are non-parallel, such that the reflected second combined beam 115, the green light beam 116 and the red light beam 117 penetrating the second polarization beam splitter 140 are directed together. Multi-band filter 150.

In the above embodiment, the second polarizing beam splitter 140 and the green light beam 116 can be prevented from causing the spectroscopic spectroscopic failure due to the angular deviation.

Referring again to FIG. 6, when the second combined beam 115 and the red light beam 117 are incident on the multi-band filter 150, the first blue light B1 in the second combined light beam 115 is reflected, and the second blue light B2 is transmitted through the multi-band. Filter 150. The red light beam (R2) 117 (with peaks between 637 nanometers (nm) and 641 nanometers (nm)) penetrates the multi-band filter 150.

Next, the green light beam 116 of the second photoluminescent device 130 has a wavelength band from 470 nanometers (nm) to 700 nanometers (nm). When the green light beam 116 is incident on the multi-band filter 150, the wavelength is at 470 nm ( Light between nm) and 536 nm (nm) and greater than 622 nm (nm) will penetrate the multi-band filter 150. In the green light beam 116 wavelength, the light intensity greater than 622 nanometers (nm) is only a partial proportion, so the second photoluminescent device 130 penetrates the multi-band filter 150 light to 495 nanometers (nm) to 536. The green light of nanometer (nm) is dominant, that is, corresponds to the green light region G1 of Fig. 5.

According to the above optical path arrangement, the second blue light B2, the green light beam 116, and the red light beam 117 are incident in parallel with each other and penetrate the multi-band filter 150, and when the second blue light B2, the red light beam 117, and the green light beam 116 After penetrating the multi-band filter 150, they will collectively form a second primary color combination (B2G1R2).

Finally, the interface between the stack 200 and the total reflection gap 206 reflects the second primary color combination from the multi-band filter 150 to the direction 102 as indicated by the arrow to complete the second primary color combination in the six primary color solid state light source 100. Output.

In summary, the six primary color solid-state light sources of the present invention output a first primary color combination and a second primary color combination, wherein the two primary color combinations respectively have blue, green, and red primary color lights.

According to the six primary color solid-state light source of the embodiment of the present invention, since the first blue light source and the second blue light source are respectively excited by the first light-emitting source and the second blue light source that are continuously illuminated, the yellow light can be greatly improved. Light and The amount of green light is activated to effectively increase the brightness of the system.
